AUTOMOBILE LAMP-GEAR.

Specification of Letters Patent.

Patented Apr. 20, 1915.

Application filed May 3, 1912, Serial No. 694,862. Renewed September 13,1914. Serial No. 862,404.

To all whom it may concern Be it known that I, W ILLIAM OSMOXD, acitizen of the United States, residing at Scranton, in the county ofLackawanna and State of Pennsylvania, have invented new and usefulImprovements in Automobile Lamp-Gear, of which the following is aspecification.

This invention relates to automobile lamp gears, the objectin view beingto provide simple and effective means capable of ready and easyattachment to the standard automobile now in common use, whereby in theoperation of turning the front steering wheels of the machine, the lampsare correspondingly turned in such manner that the rays of light fromthe lamps are directed forward in lines parallel to the path of movementof such steering wheels of the machine, with the result that the roadwayis fully illuminated in the direct path which the machine is caused totravel by reason of the angle at which the steering wheels are set.

With the aboveand other objects in View, the invention consists in theconstruction, combination and arrangement of parts, as

.will be hereinafter more fully described,

illustrated in the accompanying drawings, and pointed out in the claimhereunto appended.

In the accompanying drawings: Figure 1 is a plan view of the frontportion of an automobile, showing the application of the presentinvention thereto. Fig. 2 is a side elevation of the same, omitting thesteering wheels. Fig. 3 is an enlarged vertical section taken in linewith one of the lamp carrying shafts. Fig. 4 is a side elevation of theuniversal lover. 5 is a plan view thereof. (3 is a side elevation of thelamp bracket. Fig. 7 is a plan view thereof. Fig. 8 is a face view ofthe hearing tube, showing the means for attaching the same to thebracket head. Fig. 9 is a detail horizontal section illustrative of theconnection between the lamp shaft tube and the bracket. Fig. 10 is aplan view similar to Fig. 1, showing the device adapted for use wherethe steering arm connecting rod is located in advance of the axle. .Fig.11 is a side elevation otthe same. Fig. 12 is an enlarged plan view ofthe opcratin arm. Fig. 13 is a side elevation of the same. Fig. 11 is anend view thereof.

Referring to the drawings, 1 designates the oppositely arranged sidebars of the chassis of an automobile, 2 the front axle, 3 the steeringwheels, 4 the steering arms, and 5 the steering arm connecting rod,which is jointed to the arms at for giving parallel motion thereto whenthe steering wheels are turned, all of said parts being of the usualstandard construction and arrangement, the connecting rod 5 beinglocated in rear of the vertical plane of the front axle 2.

In carrying out the present invention, I employ in connection with eachlamp or search-light a vertical lamp carrying she-ft 6 having the usuallamp supporting yoke 01' bracket 7 securely fastened to the top thereof,so as to turn therewith. The shaft 6 passes through a bearing tube 8provided at the top with a ball bearing 9, and at the bottom withanother ball bearing 10, said center or pivot, upon which the bearingtube 8 may be turned and ad justcd, for a purpose which will hereinafterappear.

perfect working condition at In connection with each bearing tube 8, I Iemploy a supporting bracket 17 having an L-shaped pendant extension 18which bears against the outer side of the chassis, the said bracketbeing provided with a hole 19, by which it may be bolted or riveted tothe frame of the machine. At its projecting end. the bracket is providedwith a circular head portion 20 having a central hole 21 for the screw16, and a series of concentric slots 92 to receive the screws 15, thisconstruction and arrangement adapting the bearing tube 8 to be set in aperfectly vertical position and securely fastcncdin such position. Thisadds materially to the smooth working properties of the device as awhole.

Secured to the connecting rod 5, exactly in rear and in longitudinalalinemcnt with the lamp carrying shaft 6 when the wheels 3 are setperpcndiculm to the front axle 2,

are clamps 24 divided, as shown, so as to adapt them to be placed overand secured to ,the connecting bar 5, the two-parts of thedivisionalclamp being secured together by screws or their equivalent. Atthe bottom of each clamp there is a square socket tube 25 adapted toreceive a forwardly-projecting rigid arm 26 square in cross section tofit in the socket, in which it is held, when properly adjusted, by meansof a binding screw 2 Connected to the forward extremity of I each arm 26by means of a knuckle 'oint 28 is a yoke piece '29. which is connectedby another knuckle joint, at 30, to a telescopic lever, comprising aninner member 31 and an outer member or tube 32 adapted to slidelongitudinally upon the inner member 31. At its outer'end the telescopicuniversallever has connected thereto, by a knuckle joint at 33, acollar34 having a s uare hole .35

" I therein adapted to fit tight y upon. the

' ence to Fig. 2 that the frame bars 1 have an up and down movementrelative to the axle 2, on;account of being mounted thereon by:

means of the interposed s rings 37, and the telesco ic construction 0said levers permits o the free relative movement between shafts shouldbe arranged at a distance in the wheels and the frame of the machine.

. By reference to. Fig. 1, it will be observed that the forwardextremities of the arms 26 are directly in line with the axle 2, and thearms 26 should be of the same length as the universal levers, or inother words, the lamp advance. of the axle equal to the distance of theconnectin rod 5 in rear of said axle. In order to enab e the mechanismto operate smoothly, the universal levers should be of a length'exactlyequalto the steering arms 4, onwhich the wheels 3 are mounted. In

are adjuste Fig. 1, I have indicated by dotted lines the movements ofthe parts above described,

audit will be observed that it matters not at what angle the wheels 3 ofthe machine the lamp shafts will be turned a corresponding degree, andtherefore, the rays of light'from the lamps are always directed inplanes parallel to the path of movement of the steering wheels. Thisilluminates the exact portion of the roadwaywhich is to be traversed bythe automobile, and the same is accomplished, by simple mechanism notliable to get out of order, and which may be easily maintained inerfect'working condition.

he mechanism hereinabove described may be equally as well-adapted foruse in connection with the steering arm connecting rod located inadvance of the axle, as shown in Figs. 10 to 14, inclusive, wherein itwill be observed thatinstead o f.'the arm 4 projecting rearwardlyfrom'the axle, said arm,

designated as 4:, extends-in advance of the axle, the two arms 4' beingconnected by the rod 5. [Under this arrangement, the teletom of the lampshaft forward and connects to the forward end of the arm 26.. The

knuckles 38 of said arm extend rearwardly from the forward extremity.thereof, as shown in Figs. Hand 13. It will be observed that theextremity of the arm 26' is. located as far in advance .of 'fthe rod 2as said rod is located in advance of the axle 2, so that as the 'Wheels3 are turned, acorresponding movement will be given t'o'the.

lamps which will be caused to face'in the same direction as the wheels,and project their'rays 'oflight directly in the path to i be traveled bythe machine.

What is claimed is:

In an automobile, the combination with the steering knuckle lever armsand the-connecting rod joining said arms and located in parallelrelation too the front axle, of vertical lamp carrying shafts journaledin advance of the .vertical plane of the front axle,.lever arms on thelamp carryin shafts having the same'sweep or radius '0 movement asthe.knuckle lever arms, and rigid arms fastened to said connecting rodinter-- mediate of the ends thereof and extending l at right anglesthereto, the lever arms of the lamp shafts beingconnected. to saidshafts by a knuckle joint having movement ona horizontal axis only, eachof the last-named lever arms embodying telescopic sections In testimonywhereof I a'iiix my signature I in presence of two witnesses.
